What You Get: Multi-Size ICO Files

An ICO file is not a single image. It is a container that holds multiple icon sizes in one file. When you convert an image with Any2ICO, you choose which sizes to include — 16, 32, 48, 64, 128, and 256 pixels — and the converter packages them all into a single .ico file.

This matters because browsers and operating systems request different icon sizes depending on context. A browser tab might use a 16x16 icon, while a Windows desktop shortcut might use 48x48 or 256x256. If your ICO only contains one size, the system scales it, which often leads to blurry or unreadable icons.

With Any2ICO, you select the sizes you need and download a single file that works across all these contexts. Need to convert many images at once? Batch conversion lets you process multiple files and download them all as a ZIP archive.

How to Use Any2ICO

Converting an image to ICO takes three steps:

  1. Import your image — Drag and drop a file, browse from your device, paste from your clipboard, or import from a URL. Dropbox, Google Drive, and OneDrive imports are also available.
  2. Choose your settings — Select the icon sizes you want (16 through 256), pick a scaling mode (contain or cover), and set the background to transparent or white.
  3. Convert and download — Click convert to generate your .ico file. For batch conversions, download all files as a ZIP.

Any2ICO accepts PNG, JPG/JPEG, WebP, GIF, BMP, AVIF, and SVG files up to 10 MB each. The conversion produces a single ICO file per source image, with all your selected sizes embedded inside.

Settings That Matter

Any2ICO gives you control over three settings that directly affect how your icon looks:

Icon Sizes

Choose from 16, 32, 48, 64, 128, and 256 pixels. For a typical website favicon, include at least 16 and 32. For Windows application icons, include the full range up to 256. Not sure which sizes to pick? Read our favicon sizes explained guide for specific recommendations.

Scaling Mode

Contain fits the entire image within the square icon area, preserving proportions. This is the best choice for most logos. Cover fills the entire square, cropping edges if the image is not already square. This works well for photos or images where you want edge-to-edge coverage.

Background

Transparent leaves empty space clear, which works well for logos on any background. White fills the background with solid white, which can help logos remain visible on dark browser themes or system backgrounds.
